AUTOMATIC TH ERMOSTATIC VALVE.

SPECIFICATION forming part of Letters Patent N o. 664,668, dated December 25, 1900.

Application tiled May 17, 1900. Serial No. 16,984. (No model.)

T0 all 2071/0797, t may concern:

Be it known that I, JOHN E. NOBLE, a citizen of the United States, residing at Fort Wayne, in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in Automatic Thermostatic Valves; and I do hereby declare that the following is a full, clear, and exact description of theinveutiomwhich will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accom panying drawings,\vhich form part of this specication.

My invention relates to improvements in automatic thermostatic valves.

The object of my present invention is to provide an automatic thermostatic-valve-actuating mechanism specially designed to be used in connection with a valve arranged in a water-pipe line to permit the iiow of water, as in case of tire, and adapted to be actuated by the effect of heat upon a thermostatic plate or bar in operative connection therewith.

The principal novel feature of my invention is the operating of a spring by means of a thermostat actuated lever which can be practically applied to numerous uses.

In the accompanying drawings similar reference-numerals indicate like parts throughout the several views, in which- Figure l is a side view of my improvement, showing the relative arrangement of the operative parts with the valve closed. Fig. 2 is a plan view of the same, showing the valve open. Fig. 3 is an end View of the same, showing the relation of the parts of the lock when the valve is open and showingin dotted outline their Vrelative arrangement when the valve is closed. Fig. 4 is an end View of the valve-lever in cross-section. Fig. 5 is an enlarged detail side view of the triggers 19 and 15, showing their relative arrangement. Fig. 6 is a side view of the trigger 19, taken at right angles to Fig. 5. Fig. 7 is a plan view of Fig. 5 with the spring 2O removed. Fig. 8 is an enlarged detail of the tumbler and lever 23, showing the relative arrangement of the projection 34. Fig. 9 is a detail, partly in section, showing the connection of the tumbler with the spigot-valve.

From a suitable base or pedestal 1, of proper material, isl suspended a pendent horizontal thermostatic bar or plate 2, rigidly fixed at one end and having its other free end adapted to be moved laterally by the action of heat or cold and which may be adjusted to any desired position in the same horizontal plane by loosening the holding-screw 9. On the upper face of the said base l 'is rigidly fixed, in any suitable manner, a proper spigot-valve 4L, of well-understood construction, rotably mounted in a proper valve-casing 3. This valvecasingis preferably set down in a proper opening in the base 1, though this is not a mate rial matter. The valve-casing 3 is also provided with integral brackets 10 upon one end thereof, to which is rigidly bolted the angleplate 8, on which is arranged any suitable spring mechanism, preferably a gun lock mechanism, adapted to be tripped or actuated by the said thermostatic bar, thereby automatically actuating the said spigot-valve 4. This gun-lock mechanism, of well-understood construction, is arranged substantially as follows: A vertically-depending hair-trigger 19 is pivoted in the fixed plate 12, which may be integral, if desired, and Works in a vertical slot therein, the lower end of said hair-trigger being provided with a laterally-disposed thumb-screw 13, which lies in the path of movement of the therinostatic bar 2 and may in;engagement with a notch in the trigger.

`15, the tendency of said spring being to throw the toe 16 of said trigger up. When'the trigger 15 is set, the toe 16 is held down by engagement with a notch formed in the head of the hair-trigger 19, the said trigger 19 being held in place by a flat s pring 20, one end of which is fixed to the plate 12 and the other end being in engagement with a notch in said trigger 19. A iat plate or bridle 21 is bolted to the vertical portion of the angle-plate by the screw-bolts 22, so as to leave a space be- A lever 23 or scar pivtween the two plates.

IOO

oted between the two plates has at one end an arm 24, projecting at right angles thereto and projecting into the path of movement of the toe 16 on the trigger 15, the other end of the lever 23 forming a nose 34, which is adapted to engage an offset in a spring-controlled tumbler 25, pivoted between the bridle 21 and plate 8. The square end 35 of the tumbler 25 projects into a recess in the valve 4, which takes the place of the gun-hammer and is rotated in a similar manner by the tumbler 25. Pivoted to the free end of the tumbler 25 is a swivel 27, connected to the mainspring 28, as shown, the said tumbler being held against rotation or in a locked position and against the tension of said mainspring by the nose 34 engaging an oset in said tumbler, as hereinbefore described. The stem of the said spigot-valve is provided with an operating-lever 29. To a lug 6 on the outer end of the said valve-casing are fixed the ends of a wire bail-shaped spring 33, whose looped end is arranged in engagement with the said lever 29, the tension of said spring being ererted to assist in moving the said lever 29 in opening said valve. The outer free end of the lever 29 forms a plug and is adapted when the valve is opened to engage with the two insulated spring contact-points 30 of an electric signal-circuit to close said circuit and sound a gong or other alarm.

The operation of my device is as follows: In case of ire in a structure wherein my apparatus is located the heat from the same will cause said thermostatic bar to move laterally into engagement with the set-screw 13 of the hair-trigger 19 and pressing upon the same will release the toe 16 of the trigger 15, allowing the same to dy upwardly by reason of thespring 18 and strike-arm 24 of sear 23. The toe 16, striking the arm 24 of the sear 23, will cause the same to move upwardly and release nose 34 from engagement with the tumbler 25, allowing the spring 28 to turn said tumbler 25, and through the medium of the square end of said tumbler open said valve and allow the fire-extinguishing tiuid to pass on and out upon the fire. -The spring 33, exerting its tension upon the valve handle or lever 29, will tend to assist the springYV 28 in opening said valve, and said lever upon reaching its lowest point will sound an alarm in the manner hereinbefore described. To close the valve and restore the parts to their locked positions, the valve handle or lever 29 is moved up to its former position.

while I. have described my invntion in f i to'open or close electric switches and to start Y or stop clockwork mechanism or spring mof tors-and it may also be used in connections:Y g

with a three-way valve, and I therefore wishVVY Y f to reserve the right to use my invention in these and other connections. Y

Obviously the spring mechanism whichf connects the thermostat bar with the spigotY j' valve may be indefinitely varied without def Y parting from the spirit and scope of my'in-YY .7oz

vention, which consists in controlling a valve:V Y ,Y

by means of a direct connection between said; e

valve and a thermostat-actuated trigger i mechanism. Y

Having thus described my invention, whatY 7 5'"V I claim, and desire to secure by Letters Pat-V p Y. ent, is i' l. In a theremostatic valve the combina-[ tion of a spigot-valve; an actuating-tumbler connected directly to said valve, as shown; 11.2V 8o trigger mechanism connected to said tumbler;V and a thermostat adapted to release said i l mechanism. i Y g 2. The combination in a thermostatic valve l of a rotary spigot-valve; a rocking tumbler 857'.'

operatively connected with said valve, as shown a tripping mechanism connected withV i' 'f said tumbler; and a thermostat adapted to release said mechanism. i

3. An oscillatory spigot-valve in combina-1963i .valve-casing; a rocking tumbler in direct op- Vroo' erative connection with said valve; a trigger mechanism connected with said tumbler; and 'i a thermostat adapted to release said trigger 'j' 7' mechanism.
